Git height set to 0 when version.json file has wrong capitalization

I can’t make my VSTS CI use the Git height. I can’t figure out what I’m missing.

The “Get sources” VSTS task has “Shallow fetch” unchecked. I’m using a private build agent and I can see that the “.git” folder is present.
The “dotnet pack” VSTS task has “Automatic package versioning” set to “Off”.

GitVersioning: v2.1.16 Version.json:

{
  "$schema": "https://raw.githubusercontent.com/AArnott/Nerdbank.GitVersioning/master/src/NerdBank.GitVersioning/version.schema.json",
  "version": "1.1-alpha",
  "nugetPackageVersion": {
    "semVer": 2
  },
  "cloudBuild": {
    "setVersionVariables": true,
    "buildNumber": {
      "enabled": true
    }
  },
  "publicReleaseRefSpec": [
    "^refs/heads/master$" // we release out of master
  ]
}

Oh, wow. Nice catch. I’ll chalk that up to when we read the current version, we just use the case-insensitive file system to find it, but when we search git history, we are now using git which is case sensitive, so we can’t find it and treat it like it isn’t checked in.

Found the issue! It’s case sensitive! The file was called “Version.json”. Lowercasing the v makes it work. I was rulling that out because the hash was being added to the version number. Thanks for the help!
